Win-KeX VNC asking "Would you like to enter a view-only password?"

[nullroot]

First time using forums
title. Should i say yes or no to that question. NetworkChuck made a video about Win-KeX and then i wanted to do the same thing, so i installed kex and type kex in the terminal. then i typed password and verified. then the question came and i have never used VNC before. Thanks.
